title: [Effectiveness of a nursing intervention on patient anxiety before transfusion of packed red blood cells].
abstract: OBJECTIVE
  To evaluate the effectiveness of an educational intervention regarding anxiety and satisfaction in patients requiring a red blood cell transfusion.
  
  
  METHODS
  Randomised, controlled, single-blind clinical trial in patients requiring a packed red blood cell transfusion.
  
  
  METHODS
  alpha=.05, beta=.10, to detect a 10% difference, 70 subjects in each group. The sampling recruitment was randomised to the intervention group (IG) and the control group (CG).
  
  
  METHODS
  an intervention protocol with oral and written information using a published guide on the safety, risks and benefits of haemotherapy for the IG, and an equivalent one on general health topics for the CG.
  
  
  METHODS
  pre- and post-anxiety state; Spielberger's validated questionnaire: STAI. Satisfaction, by an ad hoc questionnaire. Sociodemographic and clinical variables: description, reason for transfusion, prescription knowledge, incidents, records.
  
  
  RESULTS
  There was a total of 144 subjects, 73 (50.69%) in the IG, and 71 (49.31%) in the CG. The mean age was 55.80 years, with 56.94% males, and a first transfusion in 52.08%. Comparability between the IG and the CG was tested and confirmed. The decrease in anxiety after the intervention for the IG was 19.99, compared to 25.48 in CG. The difference was greater than the proposed 10%, and was statistically significant. The preference for information was 98.60% in IG, compared to 43.70% in CG.
  
  
  CONCLUSIONS
  The hypothesis was confirmed; a protocolised nursing educational intervention protocol increased patient satisfaction with nursing care, and decreased patient anxiety, thus preventing complications and providing greater safety to the users.
